I was facing the same issue.
in file modules/fb/fb_user.module line 742

// The drupal user is a facebook user. Now, learn more from facebook.
$info = fb_api($fbu);

// The drupal user is a facebook user. Now, learn more from facebook.
$info = fb_api($fbu, fb_get_token());

worked for me.

I'm testing a slightly more flushed out patch on my D6 site. This will make it to D7 shorty.
